JOURNAL-BEARING.

SPECIFICATION forming part of Letters Patent No. 627,985, dated July 4, 1899.

' Application filed January 21, 1899. Serial No. 702,930. (No model.)

To aZZ whom. it may concern.-

Be it known that I, LEWIS P. DELANO, a citizen of the United States,'residing at the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in J ournal-Bearin gs, of which the followingis such a full, clear, and exact description aswillthe wearing-surface is composed of two dis-V similar metals, preferably arranged in spirally-disposed strips, such as is described in Letters Patent No. 597,429, granted to John Oldendorph January 18, 1898.

One object of my invention is to so construct the bearing that it can be thoroughly and efiectively lubricated Without waste of oil.

Another object of my invention is to pro vide means for renewing the wearing-surface of the bearing, thereby saving the expense of machine-work required to fit a new bearing to the bearing-box.

My invention consists in part in providing the wearing-surface of the bearing with one or more oil-grooves extending from a suitable oil-hole around the bearing to carry the oil in the direction of the length of the bearing and returning to the oil-hole, whereby the oil is distributed along the bearing without waste.

Myinvention also consists in a bearing com- I forming part of the wearing-surface, and an intermediate layer, of an easily-fusible metal, such as Babbitt metal, holding said shells together and also forming part of the wearing surface.

In the accompanying drawings, which illustrate a bearing made in accordance with my invention, Figure 1 is a plan view of a casting adapted to form the inner shell of the bearing. Fig. 2 is a vertical longitudinal section of the bearing, and Figs. 3 and 4 are cross-sections of a one and two part bearing, respectively.

fusible metal, such as Babbitt metal, which also forms part of the wearing-surface of the bearing.

The inner shell 11 is composed of Wearingstrips 13 and connecting-strips 14, which are preferably cast integral. The shell 11 may be cast in the form of a plate, as shown in Fig. 1, and bent into the form of a cylinder, or it may be cast in the form of a cylinder, as shown in Fig. 2. Formed in asuitable number of the strips 13, terminating at the oil-hole 15, are oil-grooves 16, which cause the oil to flow from one side of the oil-hole 15 spirally along the bearing and return it to the other side of said oil-hole. In forming the bearing I place the inner shell 11 around a snug-fitting shaft or mandrel surrounded by the outer shell or casing 10, so as to leave a space between the two shells, and then pour into the space melted Babbitt metal 12. The Babbitt metal 12 completely surrounds the connecting-strips 14, thus holding the shell 11 firmly in the shell or casing 10, and also forms the part of the wearing-surface unoccupied by the strips 13. In making a twopart bearing I form near the edges of the parts of the casing 10 grooves 17, as shown in Fig. 4, into which the Babbitt metal 12 flows, and thus prevents the parts of the halfbearings from becoming separated.

In operation oil is supplied to the bearing through the oil hole 15. The motion of the shaft carries the oil into one end of the grooves Ioo from each end to the center, where the oilis discharged, or extending the entire length of the journal. I am also aware that journal-bearings have been formed of perforated sheets of copper secured in place by Babbitt metal cast directly in the journal-box, and

therefore I disclaim such constructions.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, -is- 1. A journal-bearing having an oil -'hole formed therein and one or more oil-grooves formed in the Wearing-surface thereof and extending from one side of said oil-hole around and in the direction of the length of the hearing and returning to the other side of said oilhole.

2. A journal-bearing having its wearingsurface composed of two dissimilar metals, an oil-hole forlned therein, one or more strips of one of said metals extending from one side of said oil-hole around and in the direction of the length of the bearing and returning to the other side of said oil-hole, and an oil groove or grooves formed in said strips and conforming thereto. Y 3. In a.journal-bearing, an outer shell or casing for insertion in a journalbox, an in ner shell forming part of the Wearing-surface, and an intermediate layer of fusible metal holding said shells together and also forming part of the Wearingsurface. In testimony whereof I have hereunto set my hand and affixed my seal in the presence of two subscribing Witnesses.
